Hi all, I've been reading the forum for a while but finally ran into a problem that I can't fix by searching old posts so I'll post it and hopefully one of you can help.
My super m has always run great but the live hydraulic pump was pretty much blown out. I tried to take it apart and fix it up but it was too sloppy to make any decent pressure. So I bought a new pump ($ouch) and got it installed today. It seemed to be pumping great and then I went to lift my hay rake to see if it could do what the old pump or my dads m couldn't. Tractor was just above idle and It lifted the first stage of the rake like both my old pump and my dads m could but when the second cylinder activated it didn't lift it. I could hear the engine bog down a little with the pump trying but it didn't make enough pressure. So I revved it up and hit the lift lever again and it started to lift the rake but then the engine died. It acted like it lost spark instantly and just spun down to dead with a few pops from the muffler and a big backfire at the end. I tried to re start it and nothing but a lot of popping and sputtering but won't run. I pulled the dist. Cap and it's turning with the engine but acts like timing is way off. I thought maybe I skipped a tooth or a gear somewhere so I adjusted timing by twisting the dist. And after trying both ways no improvement. Also it seems to turn over odd, like un even, like I fear the cam isn't spinning or a cylinder blew or something. On the bright side though the new pump seems to work great! I just hope the tractor I put it on didn't die in the process...
